Xp desktop shows "My Computer", at least it is an option to do so.
Frankly, reading this article gave me nightmarish flashbacks about the time I had to use OS X. Closing down applications was a real pain, if I remember correctly. Clicking the "X" doesn't close them, only hide them. You have to unhide them and find the "Exit" (or whatever) in the file menu to actually close them for good (not the file menu in the window, mind you, but the one in the useless "desktop transforms into application window").
So please don't refer to OS X as an usability icon, definitely not when the question is how to shut down things.
